The City of Toronto is developing a long term water servicing strategy for the Downsview Area to provide sustainable water supply and water pressure to 2041. There is currently low water pressure in parts of the area and growth is expected, requiring infrastructure enhancements. Alternatives being considered include realigning pressure districts with new long or short transmission watermains, or booster pumping stations. Public feedback is sought on the alternatives and evaluation criteria to select a preferred option. The next steps and opportunities to provide input were outlined.

2. Why Are We Here?
• Introduce the Downsview Area long term water
servicing Municipal Class Environmental
Assessment (EA) Study
• Provide an overview of the Study’s planning
approach – Municipal Class EA Process
• Present the Study’s problems and opportunities
• Present the alternative solutions and the draft
evaluation criteria being considered
• Gather input on problems / opportunities,
alternatives, and the draft evaluation criteria
The Purpose of this Public Information Centre is to:

As you review the information presented today, we encourage you to
ask questions and provide feedback.

3. Purpose of the Study
What is the problem?
• Significant near and long term growth is expected in the
Downsview Area (the Study Area)
• Residents and businesses are experiencing low water pressure
in the Study Area, particularly in the northwest portion (near
Keele Street and Finch Avenue West)
• There is a need to enhance infrastructure for sustainable water
supply and water pressure to service the current and projected
future population within the Downsview Area
What is the opportunity?
• Improve the overall level of water servicing to meet the needs of
the existing customers and the future projected growth
• Coordination with other projects in the area such as the
Downsview Area Major Roads Project can minimize
construction impacts and provide efficiency
The City of Toronto is developing a long term water servicing strategy for the Downsview Area
to provide a sustainable water supply and water pressure to 2041.

4. Water Supply to the Downsview Area
The City’s water distribution
system is divided into pressure
districts. A Pressure District
(PD) is an area of water service
having a constant water
pressure. PDs are required due
to changes in ground elevation
for different areas. The Study
Area is serviced by PD5 and
PD6.

5. Alternative 1:
Do Nothing
This alternative involves no
changes to the existing
water network.
This alternative is screened
out for further evaluation
as it does not meet short
and long term water
servicing needs.
Alternatives 2A 2B 2C:
A Realigned Pressure
District + Long
Transmission
Watermain
There are three (3) long
transmission watermain
routing options under
consideration. Each option
will also require other
additional upgrades for the
water network.
Alternatives 3A 3B 3C:
Booster Pumping
Station + Short
Transmission
Watermain
There are three (3) booster
pumping station + short
transmission watermain
options under consideration.
Each option will also require
other additional upgrades for
the water network.
Overview of Alternatives
The following boards provide more details regarding the routing options under
consideration for Alternatives 2 (A, B, C) and 3 (A, B, C) 5
Alternative 4:
Storage (Elevated
Tank)
The alternative to provide
additional storage was
considered.
This alternative is screened
out for further evaluation
as the technical / hydraulic
study showed that the
addition of a new storage
tank would not meet water
servicing needs.

6. Evaluation Criteria
Draft criteria have been identified
that will be used to evaluate and
select a preferred alternative.
Tell us what you think!
Are there other evaluation
criteria that have been missed
and should be considered?
